Game modes are composed of many primary and secondary game modes, each represented by 2 letters. On this case we have:

APEMSO // RDEMSO-AP: All Pick > You can pick any hero, scourge or sentinel.-EM: Easy Mode > You gain gold and experience faster, and towers have lower stats-SO: Switch ON > You are allowed to use the "-switch" command to change places with another player or leaver.-RD: Random Draft > Players take turn to pick heroes, from a random pool of 20 heroes.

another mode...-apsopmfrap=All Pickso=Switch Onpm=Pooling Modefr=Fast Respwannote*if you have a master alchemist user on your team, -pm would be an advantage because -pm allows you to share and give your items to teammates, all items are sharable..^^or in other words, also stealable..part of good advice, if pm is on, always have a courier, and sponsorship is always there.. ^^fr, fast respawn make respawn time 50% less, so 60-50% = 30 seconds^^
